Has anyone used this product? Says it removes silica and phosphates. W

I've heard good things about it on here. I use Phos-x because it's cheaper but alot of people on here use phosgard.

well i hate to do it but i have to say i will never use it again. i used it to see if i could bring my phosphates down over time to lower levels and well never even touched it. but thats just my personal opion maybe it works better for others. i have heard great things about phosban from everyone though

[i have crabs]

i use it because im on tap water and it keeps the brown algae away helps with cyno but dosent always get rid of it
i would recomend using it if u use tap water but thats just my opinion

thanks for the info, I have a couple of questions:

does it have any impact on pH or other parameters?

Also, what is the best way to use it? Do you just add it to your existing filter media?

I have half a 4L sitting here going to waste. I used it in my 75G and it began bleaching my toadstool coral. I read a couple articles pointing to the aluminum based Seachem. I stopped using it and the coral recovered for the most part and thats been about 4 weeks now. I used it in my 29G (since I had no sarcophyton in it) and the corals and inverts started looking a little weird. I highly recommend using something else. I am currently testing (Two Little Fishes) Phosban which so far has been a disappointment (Using the phosban 'reactor') I also have RowaPhos on deck to try for a second time since the first time out with it provided little to no results. In the defense of the Phosban I do not think I have enough water flow for it, but I will be hooking to a 90G/Hr pump this weekend...

GL!

I used it to try and lower my phosphates in my 58 gallon. I did not have any negative effects on my corals (hard/soft) or clams but it did not cause any measurable reduction in phos. I would not buy it again.
